Anthragallol is the most active inhibitor against xanthine oxidase. | [Definition]
ChEBI: A trihydroxyanthraquinone that is anthracene-9,10-dione substituted by hydroxy groups at positions 1, 2 and 3. | [Preparation]
Commonly known as Anthragallol. (A)3,4,5-Trihydroxybenzoic acid and Benzoic acid and sulfuric acid heated; (b) in the presence of zinc chloride, heating gallic acid and Phthalic anhydride; (c) 2-Hydroxy-1,3-dinitroanthraquinonereduction in strong alkaline solution; (d)1,3-Diamino-2-hydroxyanthracene-9,10-dione and hydrochloric acid heated under pressure.
Note: The product is a free acid state paste; powdery product is sodium | [Properties and Applications]
Dark brown (chrome). (Sodium salt) was dissolved in water, slightly soluble in o-chlorophenol, (free acid) is insoluble in water, salt is not soluble in acetone, ethanol, benzene, carbon tetrachloride, cellosolve, chloroform, pyridine, toluene. The free acid in concentrated sulfuric acid is brown-red, sodium salt as a brown; diluted brown flocculent precipitate the free acid, sodium salt as an amber.
